The Role Of Neurokinin Receptors And Satellite Glial Cells In Herpes Simplex Virus 1 Latency, Andrew Jerome
The Role Of Neurokinin Receptors And Satellite Glial Cells In Herpes Simplex Virus 1 Latency, Andrew Jerome
Wayne State University Dissertations
The ability of herpes simplex virus 1 (HSV-1) to establish a lifelong infection in neurons of the trigeminal ganglion (TG) make it a constant public health threat. Viral reactivation from its latent state is currently the leading cause of viral induced blindness in the United State, as well as the leading cause of herpes simplex encephalitis. Unfortunately, how the virus is able to both establish and maintain its latent state in the TG is not well understood. The purpose of this work was to better understand how neuropeptide signaling through neurokinin receptors, as well as how satellite glial cells (SGCs) …

This body of work examined the mechanism by which SP regulates host immunity, specifically, its control of growth factors and TLR expression in the P. aeruginosa-infected cornea. The role of mTOR and VIP in corneal infection and inflammation also was tested.
SP has a dual role in bacterial infection, unexpectedly upregulating growth factor production. This was accompanied by macrophage-specific upregulation of pro-inflammatory cytokines, downregulation of anti-inflammatory cytokines, and upregulation of anti-apoptotic genes, as well as a decrease in arginase-producing macrophages (M2 cells), important in stromal healing in these mice. All of these lead to worsened disease, despite the stimulatory effects …
